We summarize the week's scientific breakthroughs every Thursday.
- Health & Medicine
Meet Sophia Upshaw, a volunteer in a coronavirus vaccine trial
In Seattle and Atlanta, scientists have started testing the safety of a potential vaccine to prevent COVID-19.
- Health & Medicine
Can fabric masks stem the coronavirus’ spread?
It’s unclear whether homemade masks made from fabric will prevent an infected person from spreading the virus to others, experts say.
- Paleontology
Two primate lineages crossed the Atlantic millions of years ago
Peruvian primate fossils point to a second ocean crossing by a now-extinct group roughly 35 million to 32 million years ago.
- Health & Medicine
Warm weather probably won’t slow COVID-19 transmission much
While some evidence has suggested higher temperatures can affect coronavirus transmission, summer’s arrival probably won’t curb the pandemic much.
- Archaeology
This is the oldest known string. It was made by a Neandertal
A cord fragment found clinging to a Neandertal’s stone tool is evidence that our close evolutionary relatives were string makers, too, scientists say.
- Health & Medicine
Can plasma from recovered COVID-19 patients treat the sick?
Researchers are racing to set up clinical trials of antibody-rich convalescent plasma from recovered patients to treat or prevent COVID-19.
- Health & Medicine
Just breathing or talking may be enough to spread COVID-19 after all
Until now, experts have said that the virus spreads only through large droplets released when people cough or sneeze, but it may spread more easily.
- Humans
Southern Africa may have hosted a hominid transition 2 million years ago
Braincases excavated from the Drimolen caves suggest Homo erectus and Paranthropus robustus may have coexisted in southern Africa.
- Math
How large a gathering is too large during the coronavirus pandemic?
Mathematical models explain why large gatherings are especially dangerous in an epidemic, and identify how large is too large.
- Health & Medicine
How coronavirus control measures could affect its global death toll
Slowing the virus’ spread will save millions of lives, but differences among countries could vary the pandemic’s toll in different places.
- Anthropology
Lucy’s species heralded the rise of long childhoods in hominids
Australopithecus afarensis had prolonged brain growth before the Homo genus appeared, but it still resulted in brains with chimplike neural structure.
- Anthropology
This 300,000-year-old skull may be from an African ‘ghost’ population
The age of the mysterious Broken Hill fossil suggests it came from a hominid that lived around the same time as both Homo sapiens and H. naledi.
